Biomass hot surface ignitersWood pellet, wood chips and biomass hot surface ignition components

50s to 1000C

Non aging

Introducing the PSx series ceramic biomass igniters range, an advance in ignition technology for solid fuels.

FKK Corporation specialises in ceramic hot surface igniters and has many years of experience of working closely with customers to develop bespoke solutions for innovative appliances manufacturers. We are a trusted supplier of hot surface ignition pro-ducts to many industry sectors.

These advanced igniters are simply the best for lighting wood pellet and biomass burners. They use only a fraction of the energy required by hot air fans and ignition blowers and will light all fuel types. Ideal for wood pellets, corn, maize, coal, coke etc.

With a considerably higher temperature, around twice that of traditional metal sheathed products, ignition times are reduced to as little as 60 seconds. This makes them significantly more economical in use.

All our range can be customized to fit perfectly in your appliance.

A fraction of the energy consumption compared to conventional heater Long lasting (non aging) Time to ignition 60~90 seconds Tested to 100,000 cycles, used for long time in Japanese market (15 years) Easy to install and retrofit Fits any steel tube with an inner diameter of 18mm 1000C at steady-state temperature Cannot overheat even with blower failure Available in 120V / 220 / 240VAC Fully electrically insulated with no exposed electric contacts UL/CE certified wiring (200 to 500C heat resistant wire) Impervious to oxidation and corrosion Dimensions: l = 96mm, d = 16mm (PSx-1) Ignite wood chips, split logs, coal briquettes or other biomass, corn etc Comply with RoHS, REACH regulation on Hazardous Subsctances

A revolutionary way to ignite biomass

Hot air stream

Hot surface 950~1050C

Ambient air stream 25C

PSx series igniters revolutionize biomass heating appliances ignition process. FKK developed several types to fit in every appliances.

Tubular radiant structure type (Blowing air system) ceramic igniters have a through hole that let air through the heating ele-ment body. With this structure ignition performance can be increase by 1.4 times compare to metal cartridge heater.

Standard radiant type ceramic igniters heat the surround air for indirect ignition of pellet.

FKK Corporation producing OEM custom order ceramic silicon nitride igniters for gas and oil energy-efficient equipments. FKK Corporation is now one of the worlds leading producers of ceramic igniters for compact boilers and tankless water heater as well as Fuel Cell SOFC/PEFC appliances, covering Asia and America .

Long Rated lifeWhile standards igniters only last 2 or 3 years, FKK ceramics igniters are made to last at least 90000 hours (nearly 10 years) according to Japanese standard and made to be very resistant in all conditions (high humidity, freezing temperatures, strong vibrations, etc.). We are the unique maker in the world to be able to design SiN igniters with average life greater than 90,000 hours in continuous operation at nearly 1400C.

High temprature, high constraintFKK ceramics igniters can reach 1400C. However, due to perfect sealing process, lead wire junction temperature do not exceed 150C.You can miniturize your system, make it safer and prolonged the rated life of other components.

FasterRising temperature is faster: up to 1000C in 8 seconds.

High efficiencyHigh-watt density discharge allow high thermic efficiency.

Superior propertiesHighly resistant to mechanical strength, high temperature strength and thermal shock.Excellent electrical insulation, dielectric strength and thermal shock resistance.

Fuel Cell Burner IgniterFuel cell SOFC/PEFC high temperature burner components

FKK provide all the Japanese Fuel cell appliances manufactures as well well as abroad MCHP SOFC systems maker with ad-vanced ceramics igniters allowing long rated life (up to 90000 hours), high reliability, high temperature (up to 1300C) and good sealing properties (lead wire temperature junction below 150-200C). With high temperature performance you save energy on start-up burner gas pre heating operation, off-gas burner exhaust gas combustion as well as air preheating.

30s to 1400C

High sealing property

Fuel Cell Igniter

High reliability and quality: over 90000 hours (nearly 10 years) of rated life, Japanese quality Very high temperature: 1350C, 1000C in less than 6s High pressure resistance and very low temperature at lead wire junction (below 100-200C) 30-60 Ohms resistance Power rating: 45-75 Watt Competitive cost: by providing major fuel cell makers, we achieved high cost/quality performance Major accounts within MCHP system integrator: Panasonic, Osaka gas,Tokyo gas, Eneos, Toshiba
